4 and 16 ohm mono inputs or 2 x 8 ohm stereo inputs. Got a few marks and dings but not what I'd call tatty. Speakers all working fine and sound great. Pickup only from Birmingham area. You're welcome to come try it out with a JCM800, JCM900, Mesa Roadking or Framus Cobra before you buy. Haggling around the asking price is most welcome.
